Application filed September 21, 1810. Serial No. 588,045.

" T all whom it mayconcem:

wire which is wbund-with equal pitch along -Be it known that I, HARRY E.Anna, a citizen of the United States, residin at Richmond, in the countyof Contra osta and State of California, have invented new and usefulImprovements in Pipe-Winding Machinesyofwhich the following is aspecification.

This invention relates to pipe winding machinery.

1 The object of'this invention is to provide an a paratus whereby woodenstave pipes may e erected at the place of their permanent location, andwired as fast as the erec-' tion proceeds by a continuous spiral coil ofthe tube as this is constructed.

A further object of the invention is to;

facilitate the constructionof a substantially jointless wooden pipe; toeconomize m the cost of the shipment of material, and

to produce a wooden stave pipe of great strength without the use ofcollars, or other joint-making devices.

This invention consists of the parts and arts as hereinafter more fullydescribed an claimed having reference to the accompanying drawin s, inwhichigure 1 isa side elevation of the winding 2 is a detailed sectionalelevation of the tension clamp, on line 2-2, Fig. 3. Fig. 3 is apartial, sectional plan on line 3-3, Fig. 2. Fi 4 is a side view of thewinding 'device s owin the tube in cross section, on

line 4-4, Flg. 5. Fig. 5 is an'edge view of the same' Fig. 6 is asectional elevation of the pitch giving shell. Fig. 7 is a detailed viewshowmg the adjustabllity of the pitch threads.

The present practice in the construction of wooden stave pipes is to cutand null all of the lumber in a mill; to erect the pi e in the mill andwind the same with suitab e r einforcing hoops or loops, and then toship the assembled pipe to the location of its erection. This method oferecting wooden pipes isextremely expensive, especially where thecomplete sections have to be shi ped great distances over, railroads,and t on ported over mountains.

By my invention it is possible to simply mill the necessary staves in anearby lumber mill and then pack these into a compact mass and haul themto the location s to be erected. Then the pipe 2 is erected where thepipe in place and the individual staves Fig. 1, are assembled withoutregards their length, care bemg taken only that adjacent abutting ointsdo not coincide. In other words, the staves are built into position toform the pipe, all of the abutting joints being staggered. this way itis not necessary to cut the individual staves to any particular length,nor do they have to be assorted as to their length, savlng consequentlya great amount of material and producing a jointless, continuous pipewhich will not become disconnected or become leaky through changes of.weather conditions or through unreasonable .ditch alinement.

For the purpose of winding the assembled p1pe I employ a suitabletrussed trestle 3 built of light but substantial constructiontemporarily supported at its ends upon suitable supports or frames 4,and provided at its lower side with a suitable track-way 5.

' Upon this track is mounted an appropriate truck 6 from which depends ayoke 6 in which is pivoted an equalizing lever 7 having upon its longerend a suitable weight 3 and at its shorter end a depending link 9,readily detachable from the end of the lever 7. Mounted upon the link 9is a pair of cheek plates 10, provided 'with gudgeons or pins 11projecting toward each other from the inside of the plates and uponwhich are mounted anti-friction rollers 12.

Upon these rollers 12 there is mounted a gear 13 recessed upon itssides, as at 14, to receive the bearing rollers 12; power beingtransmitted to rotate the gear 13 upon its supporting rollers 12 by asuitable pinion 15 to which power may be transmitted from any suitablesource, such as motor 16 or other power generating device. Securedwithin the toothed annulus 13 is a semi cylindrical shell 17 of anysuitable diameter and upon the inner surface of which are securedequidistant pitch-giving devices as triangular or V-shaped bars 18curved to conform to the inner surface of the cylinder 17. TheseV-shaped members project inwardly and substantially act as threads whenembracing the exterior surface of the staves of the pipe 2.

The operation of this portion of the apparatus is as follows: A portionof the pipe is erected and shell 17 provided with its V-shaped ribs 18is placed about the pipe as at 22, into a clamp 23, thence through the"clamp and over an arcuate wearing plate 24,

secured to the shell 17, thence through a perforation 25 in thecylinder, and onto the exterior surface of the pipe 2. One end of thewire, as at a, is firmly stapled or otherwise secured to the exterior ofthe pipe and power is transmitted through the pinion to revolve theannulus 13. This in turn carries the semi-cylindrical shell 17 aroundand around the pipe 2, and the engagement of the inclined pitchgivingbars 18 slightly biting into the exterior of the pipe 2 causes theentire wire winding mechanism to advance regularly and progressivelylongitudinally of the pipe. Any degree of tension 3 of the wire aboutthe pipe may be obtained by means of the tensionclamp 23 the upper jaw23 of which may be drawn down tightly upon the wire as indicated in Fig.2, by

means of a suitable bolt 26, or other appropriate device. It will thusbe seen, 'by referring to Fig. 1 that as the annulus 13 is driven in thedirection of the arrow that it will tightly wind the wire 20 about thesurface of the pipe 2 and by reason of the automatic spiral advance ofthe shell about the pipe 2, the cheek plates 10 and its associated truck6 will be automatically advanced along the track and trestle 3;Manifestly, the trestle 3 will be of such a length as can beconveniently handled by the operators and after the wire 20 has beenspirally wound about the pipe 2, the full length of the space betweenthe supports 4 of the trestle, the loop 9 is thrown off of theequalizing lever 7 allowing the weight of the winding device to restupon the ipe 2 and the operators then shift forward y the supports 4 andits superposed trestle 3, when the loop 9 is again placed into operativeposition with the lever, 7, and the pinion again driven thus progressingconstruction without making any joint whatsoever in the pipe 2. 1

The annulus 13 is shown as being of considerable larger diameter thanthe shell 17 and when it is desired to wind a spiral wire about adifferent size pipe 2, if the shell 17 is not of the requisite dimensionit may be removed, along with its spacing blocks 27 by which it isspaced from the annulus 13, and another shell of the properidimensionfitted upon the pi e to be wound. Manifestly for each 'di erent radiusof shell 17 the several spacer blocks 27 will vary according to thedistance between the inner surface of the annulus 13. and the exteriorof the shell 17 By this manner of mount-- ing the wiring .shell 17 I amenabled to use the same annulus upon a large range of pipes by simplyvar. ing, as before stated, the diameter of the shefl, and usingappropriate spacing blocks 27 to attach the samewit-hm the annulus 13; 0

The function of the counter-balanclng "lever and its weight 7 is toneutralize, to

the appropriate degree, the weight of the wiring a paratus upon thebody, of the pipe as the wiring proceeds thereby reducing the amount offriction of the advancing appa-v ratus on the pipe.

In Fig. 7 I have shown in detail one of the pitch-giving. bars 18 asbeing pivoted at 30 upon the shell 17 and by this pivoted pitch bar 18,the shell may be set to run either a right hand or left hand thread asdesired by simply securing the bar 18 m a corresponding angularposltion; the shell 17 being perforated as at 31 for the reception of abolt or other locking device, whereby when the adjustable bar 18 hasbeen moved to the desired angle, it may be firmly fas tened in suchposition to the shell 17. The

holes 31 are arranged upon arcs struck upon the center or pivot 30 aboutwhich the bar ivots.

Itwill be seen by referring to Fig. 1 that as the wiring apparatus,including the annulus 13 and its associated shells 17 are revolved uponthe pipe 2 that the wire 20, will be simply unwound continuously fromthe reel 21, which is mounted upon the tpipe in any suitable manner inadvance of e wire winding mechanism.

Having thus described my invention, what I claim and desire to secure byLetters Patent is 1. A wire-winding apparatus comprising a rotatableannulus, an adjustable, detachable semi-cylindrical pipe embracing shellmounted within said annulus, said shell having pitch-giving bars on itsinner surface to cause the member to advance spirally about the pipe,means for rotating said annulus, and meansfor supplying wire to thepipe.
